Default [Q] Gmail issues on stock 2.3.3

I rooted my phone and decided to free up space. One of the things I did was move updates to Gmail to /system. This caused Gmail to stop functioning. So I deleted the app (it is listed as safe to remove in various locations) and tried installing a fresh one from the market and a v2.3.4 apk, both of which install successfully but crash when trying to run (com.google.android.gm stopped unexpectedly). The v2.3.4 apk ran well for a day but then ceased to function with similar errors.

Any ideas on the easiest way to get Gmail back?
